Although triathlon bikes are almost always built with a narrower headtube for aerodynamic reasons, this broad headset style has become the standard in road bike design because it increases stiffness. The headtube tappers from a 1 1/8 th inch upper headset bearing to 1 3/8 th inch lower headset bearing. The seatpost is reversible and can position the saddle clamp so it has either 0cm or 2cm of setback. They are built with airfoil-shaped tubes sporting a 3:1 aspect ratio, which is the deepest allowed in ProTour cycling. Through the use of these technologies along with their expertise, McLaren was able to remove about 15% of the weight in the standard S-Works version-bringing the total under 950 grams-while actually increasing stiffness bottom bracket torsional stiffness.īoth the S-Works and S-Works+McLaren version are built with the same frame shape and, therefore, are aerodynamic equivalents. They also improved the environment in which the bikes are assembled, presumably by removing pollutants in the air that can imbed themselves in the frame during the layup process, to further improve the finished product. Duncan Bradley, design director for McLaren Applied Technologies, says his group used finite element analysis and stress analysis to create a “much more accurate way” to structure the layers of carbon fiber that are used to create the frame. Specialized designed the bike’s features and carbon layup for the S-Works version, but they consulted with one of the world’s foremost experts in carbon fiber design-McLaren Applied Technologies-to create a truly unique version of their new frame, called S-Works+McLaren Venge. The Specialized Venge S-Works+McLaren, posing with the McLaren F1 racecar. Specialized has combined their bike design expertise with the world-class composite manufacturing skills of the McLaren Applied Technologies group-the team that designs this F1 car-to debut Specialized’s first aerodynamic road bike, Venge, with a standard S-Works version developed entirely by Specialized and an upgraded S-Works+McLaren version that was a collaboration between the two companies.
